Air Spring Kit | Chevy/GMC 2500HD/3500HD 2WD/4WD (20-26)

Turn heavy towing and hauling into a predictable, level ride with Rough Country’s Rear Air Spring Kit designed for 2020–2026 Chevrolet Silverado 2500HD / GMC Sierra 2500HD and 2020–2026 Silverado 3500HD / GMC Sierra 3500HD models, 2WD and 4WD. If your truck sags under load or a loaded bed makes the rear end look nose-down, this kit delivers the leveling solution you’ve been missing—keeping your cab level, your trailer controlled, and your drive smoother from job site to home.

Why level matters when you’re hauling or towing

An unlevel rear can compromise steering, braking, and trailer control, increasing sway and placing more stress on your springs. This air spring kit uses two RC-branded double convoluted airbags to precisely lift and level the rear, so the truck maintains proper geometry whether you’re on the job site or on the way home.

Why this kit stands out

• Dual double-convoluted airbags: Two robust air springs work in concert to even out heavy payloads and trailer tongue weight, delivering consistent leveling across a wide load range.
• DOT-approved airlines: Quality, safety-compliant lines designed to perform reliably under demanding conditions.
• 1/4" push connector fittings: Simple, secure connections that keep the system tight and leak-free.
• All necessary bracketry included: Everything you need for a fast, sturdy installation without hunting for extras.
• Up to 5,000 lbs of load support: Real-world capacity to minimize sway, reduce bottoming out, and improve steering and braking when towing or hauling heavy loads.

What you’ll notice in everyday use

• Level stance under load: Keeps the cab and the trailer level, improving overall handling and comfort on the road and job site.
• Enhanced stability: Less sway during braking and cornering means more confidence on highways and rough terrain alike.
• Better ride quality with payload: Softer, controlled response to payload or heavy bed contents preserves control over uneven roads.
• Protects your rear suspension: By sharing the load with air springs, leaf springs experience reduced stress during heavy-duty tasks.

Who this kit is ideal for

• Truck owners who routinely haul heavy equipment, materials, or gear in the bed and need dependable leveling when towing.
• Fleet operators and contractors who rely on consistent performance under varying loads and road conditions.
• Anyone seeking greater trailer stability, smoother braking, and improved steering control on long hauls.
